Reaction Steps
MeMgBr (45.6 mL, 137 mmol, 3M in ether) was added to a mixture of the title compound from Step 2 (13.5 g, 45.6 mmol) and CuBr-Me2S (1.61 g, 7.74 mmol) in THF (150 mL) at −5° C. The reactions was stirred at rt for 2 h. It was then poured onto a solution of NH4Cl (55 g, 1.04 mol) in water (200 mL) and extracted with DCM (3×150 mL). The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure to give the title compound (6.66 g, 90%) as a brown oil. 1H NMR (400 MHz, CDCl3): δ 7.09-7.02 (m, 2H), 6.82-6.78 (m, 2H), 3.93-3.87 (m, 1H), 2.84-2.72 (m, 2H), 2.02-1.96 (m, 1H), 1.81-1.61 (m, 3H), 1.04 (t, J=7.2 Hz, 3H).
